Abstract (en)

[origin: WO9639940A1] A blood processing system (10) and associated method include a first variable volume chamber (12) to hold blood and a second variable volume chamber (16) to hold additive solution for blood. The system (10) and method further employ a separation device (50) to remove undesired material from blood. An actuated element (52) exerts external force simultaneously upon both first and second variable volume chambers (12, 16) to expel a first flow of blood from the first variable volume chamber (12) and a second flow of additive solution from the second variable volume chambers (16). The system (10) and method mix outside the first and second variable volume chambers (12, 16) the blood flow with the flow of additive solution to create a mixed flow comprising blood and additive solution. The system (10) and method direct the mixed flow of blood and additive solution through a filter (40) to remove undesired matter from the blood.
